Description
Key Features & Typical Use
Open-circuit operation
A fixed displacement pump for hydrostatic drives in open circuits. Match the inlet conditions and circuit arrangement to the approved technical data.
Bent-axis construction
The axial piston, bent-axis design offers a compact pump layout with high power density for mobile and industrial hydraulic installations.
Speed-dependent flow
For a fixed displacement, output flow varies with drive speed and volumetric efficiency. Confirm your required flow at the intended operating speed.
Configuration matching
Choose the shaft, mounting flange, rotation, seals and service-line ports for the installation. Nominal size alone does not establish compatibility.

A2FO Series — Fixed Displacement Power for Open-Circuit Systems
The A2FO is a fixed displacement pump with an axial piston, bent-axis design. It is intended for hydrostatic drives in open circuits and is used in mobile machinery and industrial hydraulic installations.
Flow depends on displacement, drive speed and volumetric efficiency. Select the pump around your required operating point, then check the shaft, flange, rotation and connections against the installation.
The product’s compact design and drive shaft bearings support its intended mobile and industrial use. Final operating limits must be confirmed for the selected configuration.

1)the values shown are valid for an absolute pressure(Pabs)of 0.1 MPa at suction inlet S and when operated on mineral oil (with a specific mass of 0.88kg/L)
2)by increase of the input pressure (Pabs>0.1 MPa) the rotational speeds can beincreased to the max. admissible speeds nmax limit (speed limits)(see diagram page 99)
Determining the size
| Flow | qv=(Vg ∙ n ∙ ηv) / 1000 | I/min |
| Torque | T=(Vg ∙ Δp) / 20 ∙ π ∙ ηmh | Nm |
| Power | P=(2π ∙ T ∙ n)/60000=(qv ∙ Δp)/600 ∙ ηt | kW |
Vg = Displacement per revolution in mL/r
Δp = =Differential pressure in MPa
n = Speed in rpm
ηv = Volumetric efficiency
ηmh = Mechanical-hydraulic efficiency
ηt = Overall efficiency
